Carcinogenicity : In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possible human
carcinogen). This classification is given to chemicals for which there is inadequate
human evidence, but sufficient animal evidence on which to base an opinion of
carcinogenicity. The classification is based upon the development of lung tumors in rats
receiving chronic inhalation exposures to free carbon black at levels that induce particle
overload of the lung. Studies performed in animal models other than rats did not show
any association between carbon black and lung tumors. Moreover, a two-year cancer
bioassay using a typical toner preparation containing carbon black demonstrated no
association between toner exposure and tumor development in rats.
